I thought this was a cool photo, testing out how well my manual photography exposure skills were working.
Construction grinding work
While taking this photo, I guess I was being observed by 2 HSE supervisors. I don’t know, maybe they though I was running a HSE investigation. Anyhow, they tailed me till I left the site, though they didn’t interfere with the work I was commissioned to do there. Very nice of them.
In the spirit of safety, notice that the grinding area has been barricaded off with tape

I wish I could use that on my client’s skull.
Their skull are so thick the grinder probably wears out before I finish my presentation !
